Title: Optical information recording and reproducing device
Inventor: TOMINAGA HIDEKAZU
IPC: G11B7/09
Filed: 1988-12-15
Abstract: PURPOSE:To obtain an optical information recording and reproducing device capable of correcting always accurately an eccentricity by specifying an address from a value of a counter and sending out a data automatically even when a CPU is under interruption inhibition. CONSTITUTION:The data Xi corresponding to an eccentric amt. is A/D-converted and supplied to the CPU 5. The CPU 5 is interrupted by a clock signal 3 at each prescribed angle of a motor 1 so that the data Xi is fetched, and the counter 6 is counted up, and then the data is written to a dual port RAM 7a by the counter 6. At the time of writing, an arithmetic processing with prescribed conditions is carried out on the data to be stored as an error data by the CPU 5. The address error data specified by the counter 6 is read out from the RAM 7a by the clock signal 3 and latched by a latch circuit 8, and then via a D/A converter 9 the data becomes an error data Xo for correcting the eccentric amount to be injected into a servoloop. Consequently, even when the CPU is under interruption inhibition, the address is specified from the value of the counter to send out the error data of the eccentric amt. synchronized with the rotation, thus correcting accurately the eccentricity.

Title: Resin mold
Inventor: SUZUKI TOMIYUKI
IPC: B29C45/38
Filed: 1988-12-14
Abstract: PURPOSE:To cut and remove a product positively at a boundary from a gate by forming grooves in the surface defining a gate of a mold provided with a product ejector pin and a runner ejector pin. CONSTITUTION:A cavity 3, a gate 4 and a runner 5 are formed between molds 1 and 2. A plurality of product ejector pins 6 and a pair of runner ejector pins 7 are inserted into the movable die 2 in a manner to be movable up and down. If a plurality of grooves 20 are formed approximately parallel to the separating face of the mold at the surface defining a gate, a molten material injected into the gate 4 flows also to the grooves 20 and is hardened, so that a gate B is strictly fixed to the surface of the mold 2 defining the gate. Therefore, when the product ejector pins push up a product A to cut and separate the same at the boundary from the gate B, even if the gate B is pulled by the product A, the gate B is not off the surface defining the gate easily. As a result, the product A can be positively cut from the gate B at the boundary without breaking the middle part thereof.

Title: Transmission gate
Inventor: ANDO KAZUMASA
IPC: H01L27/092
Filed: 1988-12-15
Abstract: PURPOSE:To prevent the transmission of an AC signal to the output even when the signal is inputted when a transmission gate is turned off by connecting a plurality of MOSFETs in series and electrically insulating forming areas of the MOSFETs on a semiconductor substrate from each other. CONSTITUTION:N-type well-like areas 12 and 13 which are respectively independent from a P-type Si substrate 11 are formed on the substrate 11. A sufficient interval is required between the areas 12 and 13 so that the first- and second- stage transistors(Tr) can be insulated electrically from each other. P-type source areas 14 and 21, drain areas 15 and 22, and N-type subareas 16 and 23 are respectively formed in the areas 12 and 13. In a transmission gate having such constitution a depletion layer capacitor is formed between the area 12 and a drain terminal 18 when a voltage higher than a prescribed level is applied across a source terminal while the Trs of the gate are turned off. If an AC signal or noise is inputted to an input terminal when the depletion layer capacitor is formed, a change in potential is transmitted to the source terminal. However, since the potential is attenuated, the substrate potential at the second-stage Tr does not change.
